“The ring, the ring that became the Horcrux, Marvolo Gaunt said it had the Peverell coat of arms on it! I saw him waving it in the bloke from the Ministry’s face, he nearly shoved it up his nose!”
“The Peverell coat of arms?” said Hermione sharply. “Could you see what it looked like?”
“Not really,” said Harry, trying to remember. “There was nothing fancy on there, as far as I could see; maybe a few scratches. I only ever saw it really close up after it had been cracked open.”
Harry saw Hermione’s comprehension in the sudden widening of her eyes. Ron was looking from one to the other, astonished.
“Blimey… You reckon it was this sign again? The sign of the Hallows?
“Why not,” said Harry excitedly, “Marvolo Gaunt was an ignorant old git who lived like a pig, all he cared about was his ancestry. If that ring had been passed down through the centuries, he might not have known what it really was. There were no books in that house, and trust me, he wasn’t the type to read fairy tales to his kids. He’d have loved to think the scratches on the stone were a coat of arms, because as far as he was concerned, having pure blood made you practically royal.”
“Yes… and that’s all very interesting,” said Hermione cautiously, “but Harry, if you’re thinking what I think you’re think—”
“Well, why not? Why not? said Harry, abandoning caution. “It was a stone, wasn’t it?” He looked at Ron for support. “What if it was the Resurrection Stone?”
